摘要
为消除近极低轨道小星载合成孔径雷达(SAR)参数偏移,基于姿态控制动力学模型,研究了偏航导引控制对滚动和俯仰通道动力学耦合的影响。理论分析和仿真试验的结果表明,其影响小于卫星所受的环境干扰力矩。在控制系统设计时,可视为干扰力矩进行处理。
To eliminate the parameter shift of spaceborne synthetic aperture radar in small near polar orbiting satellite, the influence of the yaw steering control to dynamics coupling features in rolling and yaw channel was analyzed in this paper. The results of the theory analysis and simulation showed that the influence was smaller than that made by environment disturbing moment for the satellite. It could be treated as the environment disturbing moment in the design of control system.
